There is a total of 600 children in a school. 80 of them like blue. There are 50 more children who like red than blue. Some children like yellow. The remaining 1/4 of the children like green. Find the ratio of the number of children who like green to those who like yellow
blue = 80
red = 130
1/4 of the 600 = 150 like green
That means yellow = 240
150/240 = 5/8
